To see the current release running on your system, use the PMM Upgrade panel on the Home Dashboard, or run:

podman exec -it pmm-server \
curl -ku admin:admin https://localhost/v1/version

(If you are accessing the podman host remotely, replace localhost with the IP or server name of the host.)

Perform a backup.
Update PMM tag.

Edit ~/.config/pmm-server/env and create/update with a new tag from latest release:
```
sed -i "s/PMM_TAG=.*/PMM_TAG=2.33.0/g" ~/.config/pmm-server/env
```

Pre-pull image for faster restart.

source ~/.config/pmm-server/env
podman pull ${PMM_IMAGE}:${PMM_TAG}

Run PMM.
```
systemctl --user restart pmm-server
```
